Being a modest size 10 to 12, I was intrigued to see if I could pull off a rounder rear like Kim’s – with the help of a somewhat primitive “big booty fake butt costume” courtesy of Amazon.

It took a sturdy pair of Spanx and several safety pins to hone those soft padded cheeks into a more realistic bum shape – and another willing pair of hands (THAT was awkward) to keep it in place while I tugged my clothing over it.

I decided to try out my new backside with copycat Kim outfits – after all, they’re tried and tested – but matching my size 10 top half with a size 18 rear proved tricky.

Larger dresses accommodated the butt but were baggy and shapeless around my waist and I constantly had to keep hoisting up my trousers to keep them from slipping down my hips as they battled to accommodate my ample curves.

I’ve certainly got a newfound respect for Kim’s stylist for finding clothes that fit her figure so well – the high street didn’t quite cut it for me.

Funnily enough, that’s not the only impracticality of having a disproportionately big booty.

I was easily the most unpopular person in the busy office canteen at lunch time. As I went to pull out the chair far enough to accommodate my huge buttocks, I had to ask the person sitting at the table behind me to squidge in a bit. Twice.

It certainly piqued the attention of a group of pensioners on a day out, who admitted they couldn’t work out if my “posterior” was real or not.

Suffice to say they were relieved when I informed them it was fake – with one admitting she couldn’t imagine what it would be like to have to carry that sort of weight around all day. Not easy, I can tell you.

Having a big ass wasn’t all bad. One woman with a naturally curvy rear end stopped me to ask what my secret was – and even posed for a photo to compare derrieres.
